Nascere da una cellula del corpo. Il dibattito sulla rilevanza morale delle cellule somatiche alla luce dei nuovi scenari riproduttivi

Abstract

With the scientific and technological development and the refinement of new reproductive technologies it becomes increasingly difficult to distinguish a somatic cell from an embryo. We already have new reproductive technologies, such as nuclear cloning, which demonstrate the ability of somatic cells to produce new individuals (we have not only animals but also human embryos produced by cloning). In the coming decades we may have other reproductive technologies that can further confirm the totipotentiality of our somatic cells. Some of these could be used by those who want to have a child, others seem less interesting from this point of view, but could still be used to produce human embryos to be used for research and experimentation purposes. This new scenario has important consequences at a moral level and, in particular, for the bioethical debate on issues concerning the relevance of the embryo. Since the fertilized egg cells (zygotes) and somatic cells have the same potential (in the presence of the right conditions, that is, they can become new human beings), one cannot attribute moral relevance to embryos and deny moral relevance to somatic cells.
